To all w lt om it mag co'ncern:

Be it known that I, Lnwrs C. PIKE, a citizen of the United States, residing atZellprovide agrease tube permianently assowood, in the county of Orangefand' State of Florlda,.have invented certam new and useful Improvements 1n Lubricat ng De vices, of which the following isa' specification.

7 1 This invention relates to alubri'cating device and the primary object is to provide a device for supp'lyln'g grease and oil to the axles of a wagon whereby thewheelsmay be lubricated without the necessity of .first removing the wheels" froi'n the axle.

One of theobjects of the. inventionflis to ciated with eachwheel "ofthe vehicleand extending throughthe hub thereof to communicate with the spindle or axle; the, intake opening for the pipe beingdisposed' for receiving a flexible supply pipey-carried by the portable grease container. 5

The invention further contemplates the provision of a portable grease container designed to be removably mounted upon the wagon body, the grease container provided with a means for'ejecting the grease through a flexible hose'carried by the container and adapted to be connected to the grease tube on the wheel hub whereby the grease may be forced through the flexible hose and into the interior of the hub for profusely lubricating the same. 7

A further object of this invention is the provision of a lubricating device which consists of comparatively few parts and is simple in construction, but durable and well adapted to withstand the rough usage to which devices of this character are ordinarily subjected.

'For a full description of the invention and the advantages and merits thereof, reference is to be had to the following description and the accompanying drawings, wherein is illustrated the preferred form of my invention, in which;

Figure 1 is a front elevation of a fragmentary portion of a vehiclewheel showing the grease tube mounted on the hub.

Fig. 2 is a section on the line 22 of Fig. 1, showing the flexible hose connected to the grease tube for supplying a quantity of grease to the hub.

Fig. 3 is an enlarged detail view of a portion of the grease tube.

Referring to the drawing,wherein is illusp e t of let e s a nt- BatentedrNove25,1919.

;trated the preferrectform of my invention,

and in which'likenumerals of reference indicateicorrespondmg parts throughout the sever.al views, the wheel has the usual hub. 1 and the spokes 2 radiating therefrom. Ad- 7 ja'ccnt the inner end 1 isfa radiallyextend- *ing opening 3 in communication with the interior bore 4 of the hub. .A grease tube -.5 is extended throughthe': opening 3 and 'hasits end terminating at*t he wall-of the bore" 4 thereby establishing communication between the exterior and the interior of the hub; ""The tube 5 is bentat right angles and has" its outer; e nd projected :outward'ly through the spacebetweentwo ofthe spokes ,2 and the terminal of .the tubeis extended 1 Q1 efhm1-0P eins fo m d inas p f n plate' 6 "the opposite ends of-which arei'fastened rto the, adja'cent'spolies. 'Outwarfdly 'beyond the plate '6, theltube has fits extreme terminal"screiii fthreaded toreceive a cap-"7 for 'closing the same after receiving a sup ply of grease or lubricant. This arrangement of the pipe of grease tube 5 permits one end of the tube to be disposed at the inner end of the interior bore 4 while the opposite end may be disposed at a convenient point for receiving a lubricant from the outer side of the wheel.

For the purpose of supplying grease to any one of the wheels on the vehicle, I provide a portable grease container 8 constructed in the form of a cylindrical piston. A cap 9 is secured in any preferred manner to the open end of the piston and this cap is adapted to be removed for refilling the container when the same becomes empty. A central screw threaded opening in the cap 9 receives a screw threaded piston rod 10 the inner end of which is provided with a substantially spherical-shaped member 11. A

piston 12 is mounted for reciprocatory movement in the cylinder and a stud 13 is inspherical member 11 is rotatably fitted. For

retaining the spherical member within the recess let I provide a bearing plate 15 adapted to fit over the curved portion of the spherical member where it joins the end of the piston and provided with bolt holes for receiving the fastening bolts which are secured to the end of the stud13. The outer end of the piston rod 10 carries a handle 16 by which the piston may be rotated.

Detacha-bly connected to the bottom end of the container is a flexible hose 17 which has one end provided with a nipple 18 having interior screw threads for receiving the screw threads on the end of the tube 5/ The portable grease container may be anonnted upon any convenient placeon the wagon body and when any of the wheels re'' quire lubrication, it is merely necessary'to detach the grease container from the vwagon body and afiix' the hose to the grease tube 5 through the 1'nedium ofthe nipple 18 asshown in Fi 2 of the applicants drawing, whereupon the piston rod may be actuated for forcing the grease out of the container and into the tube 5 thereby supplying grease for freelylubricating the axle or spindle.

Rotation of the wheel may continue during supplying of the lubrlcant to the axle and the portable grease container need not be removed while the nipple is changed from onerwheel to another. In tlns'mannerfthe grease container may be permanently fixed, if desired, to any convenient place on the wagon body.

From the foregoing it will be observed fthat a Very simple and durable lubricating 1 device has been provided, the' details or 'which embody the preferred form. I desire it to be understood however, that slight changes in the minor detailsyof construction maybe made without departing from r the spirit of the inventionor the scope of the claim hereunto appended.

I claim: i

provided with anopening, an angularly "disposed grease tube arranged so that one angular portion thereof engages the opening in, t the hubwhile the other angular portion pro jects in, a substantially horizontal plane throughgthe opening in the bracket sofas 1 to be approximately parallel to the hore of the hub, and closure means for engaging-the projecting'end of the tube and adaptedjupon being t1ghtened thereo n,- to cans'ethe o ppov site angular portion of the grease 'tubetobind against thewall of the opening formed in the hub, and being more rigidly 'r'etalnecl therein.
